Posterior distributions for the model parameters determined from fitting synthetic data. Left: pairwise distributions for the coherence timescale parameters τ_i. Center: pairwise distributions for the phase fluctuation magnitude parameters σ_i. Right: posterior distributions for the visibility phase parameters ϕ_ij. For all two-dimensional distributions, the red contours enclose 50% and 90% of the posterior probability. Blue lines represent the input values used when generating the synthetic data.
